differential is the easiest but what I would do is have two modified servos and one wheel on each side of the bot. Then one caster wheel for balance. Meaning, differential but with one wheel on each side
lol thats like in one of the tutorials right?~smash
YAY for diff drive!!! moving on....well for the h-bridges .. how do you plan on picking up the objects? like claw? magnet? suction
its a h-bridge so yes it allows it to go both ways...how do you plan on making a claw...theyre extremely hard.. i would recommend suction or magnetics.

I also saw something called the L293 chip that can be used for controlling? How good is that..
Have you looked at servos yet? I think that would be the optimal to go for in this case. An unmodified servo is made for these kind of movements. It will give you a simple interface to control: you simply send the position (perhaps angle would be more accurate) to the servo will align itself to that position.
That was the point of this thread.. do you have experience with both.. and in that case what would you recommend? servo or differential drive?
You don't understand. You can modify a servo for it to go like a regular motor , the advantage is the servo already has built in gearing and drive circuitry http://www.societyofrobots.com/actuators_modifyservo.shtmlSo you have two modified servos for the drive wheels and have a servo for the claw.
